In mathematics teaching in junior h

In mathematics teaching in junior high school, teachers should conceive teaching plans from the perspective of mathematical modeling, because we want to help students to constantly experience the reality of problems into mathematical models and explain and apply them. The process of "modeling" is actually the process of "mathematization". The basic requirements of mathematical modeling teaching are that teachers choose reasonable modeling problems, carefully create the situation of problems, guide students to explore actively, give play to their imagination and creativity, and provide reference and Suggestions for students. Mathematical modeling is an important way to encourage students to "learn by doing". In modeling teaching activities, teachers should timely guide students, trust them, dare to let them "do", and give them the right to choose their own problem-solving methods. Teachers are the organizers and participants of modeling teaching activities, rather than simple model, evangelist. Therefore, the implementation of mathematical modeling teaching is bound to challenge the traditional role of teachers, leading to changes in teaching philosophy and teaching behavior.In addition, to carry out mathematical modeling teaching, teachers themselves must have extensive knowledge and higher professional quality. Such as: a, on the understanding the history of mathematics science and dynamic, constantly learn some new mathematical modeling theory, and try to study how to apply the junior middle school mathematics knowledge to real life, often to delve into teaching material, the research contains the contents of teaching material, to explore mathematical modeling teaching material, in addition to the mathematical modeling activities combined with the current teaching material research note also strengthen the contact with other disciplines. Second, it is necessary to have a high professional knowledge of mathematics, especially advanced mathematics knowledge, in order to be able to use a high point of view to view the practical problems of mathematics, to find the material in real life. Third, it should have a high level of education and teaching, be good at controlling the teaching process, guiding students to carry out activities such as discussion and research, be good at inspiring students' thinking activities and improving students' metacognitive ability. It has a high teaching art, which can timely induce students' curiosity, stimulate students' thirst for knowledge, cultivate students' exploration ability, and create an active learning space for students. Fourth, it is necessary to have a high scientific research ability, especially in the teaching of modeling teaching methods to strengthen the research, understand the important ideas and basic methods of mathematical modeling, the construction of mathematical modeling consciousness and the cultivation of students' creativity to unify.
